For the next 200,000 years rainwater seep into the natural cracks of the Escabrosa limestone slowly dissolving passages and chambers within it . Each moving free fall of H2O slowly releases the minerals within the opening to make the magnificent colors and speleothems that are find throughout Kartchner Caverns . Since these speleothems are still farm , Kartchner Caverns is considered a " living cave . "
